Runner Xrunnerless alpine plants gave runner-producing plants in Fi and 

 both runner and runnerless plants in Fj, the runner being a marked dominant. 

 Runnerless white-fi-uited plants crossed with runner-producing re<l-fruited 

 plants gave red-fruited in Fi and 70 red-fruited plants to 20 white-fruited in F»

Vine pruning in California, I, F. T. Bioletti {California l^ta. Bui. 2Jfl, pp. 

 JfS, figs. 2i).— This is the first of a series of two bulletins dealing with the 

 pruning of Vitis viuifcra varieties of grapes. The present bulletin, which dis-

 more skillful grape growers and the result of experiments and observations of 

 the station workers. 



Under the general heading of principles of pruning consideration is given to 

 physiological principles of pruning; winter pruning; summer pruning, including 

 disbudding, thinning of shoots and topping of young vines, suckeriug, water 

 sprouting, pinching, topping, defoliating, thinning the fruit, ringing, and cutting 

 the surface roots; restriction and treatment of wounds; supports; pruning 

 tools; and principle of economy. 



Introductory considerations include a discussion of the results of defective 

 pruning and the habits and characteristics of the vine, with special reference 

 to Vinifera varieties.

 various direct bearing hybrid grapes with reference to their character, growth, 

 resistance to mildews, insect attacks, etc. (E. S. 11., 28, p. 840). 



Viticulture in Algeria, C. von der Heide {Landio. Jahrh., 45 {1913), No. 3,

Planting in Uganda, E. Bkown and H. H. Hunter {London and Dublin, 

 1913, pp. XVI-{-176, pis. 35, figs. 9).— A guide to the establishment, culture, and 

 management of plantations in Uganda. The subject matter embodies the expe-

 The results secured with various plants used as green manures during the past 

 4 years in plantations of coffee, rubber, cacao, etc., at the experimental gardens 

 are reported. 



The banana, its cultivation, distribution, and commercial uses, W. Fawcett 

 {London, 1913, pp. XI -{-287, pis. 8, figs. 10).— X handbook of Information on the

[Cacao manurial plats in Dominica], H, A. Tempany (Imp. Dcpt. Agr. West 

 Indies, Rpt. Agr. Dept. Dominica, 1912-13, pp. 24-34, pi- 1). — As in previous 

 years the results from the long-continued fertilizer and mulching experiments 

 with cacao (E. S. R.. 29, p. 42) show tliat natural organic manures, either in 

 the form of pen manure or compost, are superior to any other form of fertilizer 

 if they can be obtained in sufticient quantity. When sullicient organic manures 

 are not available they may be supplemented to advantage by artificial manures 

 containing nitrogen and phosiihate.
